  • Patent number: 9004094
    Abstract: The present invention concerns a valve (1), a valve closing body (14) and use of a valve (1) and a valve closing body (14) of the type used for injecting dry powder which is mixed with liquid, and where the dry powder is supplied under the liquid surface in a mixing vessel (11) in which a vacuum is typically maintained. The novel feature of a powder valve (1) according to the invention is that a closing body (14) of the valve in the closed position extends through the valve seat (13) of the valve and into the wet environment. It is hereby achieved that when the valve (1) is opened, powder or dust from powder is not deposited on the valve closing body (14). This is in spite of the valve closing body (14) being wet, due to contact with the liquid to which the powder is added. Due to its elongated shape, the valve closing body (14), which in the withdrawn position opens for inflow of powder, has the property that the inflowing powder dries the valve closing body (14) at first and keeps it dry subsequently.

  • Publication number: 20150027553
    Abstract: Apparatuses and methods for urea dosing of an exhaust after treatment system are disclosed. Exemplary apparatuses include a chamber configured to receive pressurized gas at a first inlet, receive urea solution at a second inlet, and provide a combined flow of pressurized gas and urea to an outlet, a flow passage extending from the first inlet to a seating surface, and a valve member configured to move between an open position in which the valve member is spaced apart from the seating surface and a closed position in which the valve member contacts the seating surface. As the valve member moves from the open position to the closed position the valve member contacts the seating surface at a first location and wipes an area of the seating surface extending from the first location in a direction toward the flow passage.

  • Patent number: 8887764
    Abstract: A faucet comprises a spout, and a valve assembly that can be positioned in at least three different positions so as to draw water from a cold water reservoir, a hot water reservoir and lukewarm water reservoir. The valve assembly may comprise three valves, one valve for opening and closing the flow of water between each valve and the reservoirs. The lukewarm water reservoir receives water from the cold water reservoir which sits therein and raises up to room temperature. At least one handle provides for controlling the valves of the faucet so as to draw water from each reservoir or simultaneously from at least two reservoirs. A plumbing system including the faucet, conduits for each reservoir and a lukewarm water reservoir is also provided.

  • Patent number: 8869816
    Abstract: A mixed water control valve for a faucet includes a valve housing, a control unit, and a balance unit. The valve housing has a mounting seat which has a receiving chamber and two water inlet holes. The balance unit includes a fixed sleeve secured in the receiving chamber, a pressure regulating sleeve movably mounted in the fixed sleeve, a balance baffle mounted in the pressure regulating sleeve, and two elastic members each mounted in the pressure regulating sleeve and each biased between the balance baffle and the mounting seat. Thus, the balance baffle is compressed between the elastic members which provide a buffering force to counteract a larger pressure applied on the balance baffle, so that the pressure regulating sleeve is moved smoothly and stably without producing resonant noise in the faucet.

  • Patent number: 8844567
    Abstract: A manifold, for a refrigeration system, includes a body comprising a bore hole extending through the body, and a plurality of ports including a first process port for adding and removing refrigerant, and a first side port for mechanical connection thereto. The manifold also includes a first ball valve disposed in the body, between the first process port and the first side port. The first ball valve includes a ball recess aligned with the bore hole through the body, and a ball port extending generally transverse to the ball recess and in fluid connection therewith. The ball port includes a narrow end and wider end. The first ball valve is moveable between an open position in which the ball port is aligned with the first side port and the first side port is in fluid connection with the bore hole through the body, and a closed position in which the ball port is out of alignment with the first side port.

  • Publication number: 20140263699
    Abstract: A dual input valve includes a valve stem having a compressed air valve that includes a captured o-ring held in a circumferential groove. A catalyst valve is also on the valve stem. The housing has a catalyst input port in fluid communication with a catalyst valve seat, a compressed air input port in fluid communication with a compressed air valve seat, a mixing area in fluid communication with the catalyst valve seat and the compressed air valve seat, and an output port in fluid connection with the mixing area. A spring urges the valve stem towards a closed position in which the compressed air valve closes against the compressed air valve seat blocking flow of a catalyst from the catalyst input port into the mixing chamber and the catalyst valve closes against the catalyst valve seat blocking flow of a catalyst from the catalyst input port into the mixing chamber.

  • Publication number: 20140261809
    Abstract: A valve provides multiple channels that allow alternating, or in some cases, simultaneous, fluid flow functions to a port of an instrument, without the requirement of manual manipulation of the valve by the user. A floating member such as a ball having magnetic affinity for a portion of the valve is positioned in a home, or normal, position by a magnetic field, where it remains until acted on by fluid pressure. The ball in the home position opens other channels of the device. Under fluid pressure in the channel in which the ball's home position is located, the ball is displaced, obstructing at least one of the other channels, while opening the channel to permit a fluid flow through the channel. When the fluid pressure in the channel is terminated, the ball returns to the home position, and other ports are opened.
